SPINNING on TWISTINGYFRAME.

Application filed February 3, 19,22. Serial No. 533,797.

To 1r/ZZ whom it may concern.' Y

Beit known that I, HERBERT G. BEEDE, a. citizen of the United States of America, and resident of Pawtucket, in the county ofy Providence and State of Rhode Island, have invented new and useful Improvements in Spinning or Twisting Frames, of which the following is a speciication.

This invention concerns spinning or twisting frames and relates more particularly to safety .locking mechanism for the head end ,doors Vand draft gearing bonnets of such fframes, whereby the opening of suoli doors and bonnets is positively prevented during the normal operation of the frame.- y

The device of the present invention is intended as an improvement. `upon. the mechanism disclosed in the patent to Beede, 1,064,281, June 10, 1913, andthe object of the invention is to provide a. simplied mechanism having fewer parts than that of the above patent, but without sacrificing any of the advantages of the patented device, and which at the same time shall be thoroughly reliable in action, relatively cheap to construct, and easy tok install.

In the accompanying drawings there is illustrated, by way ofexample, one'embodiment of means suitable for` carrying the above object into effect, and in such drawfl f showing the parts as positioned when the machine stops;

Fig. 3 is a similar view but illustrating the parts in the position which theyassume when the machine is stopped and the head end door and the draft gearing bonnet are open; y Fig. 4 is a plan view partly in section of the device as shown in Fig. 1;

Fig. 5 is a fragmentary vertical cross section on a line such as 5 5 of Fig. 3;

Figs. 6 and 7 are side elevations of a latch device and stop therefor employed in holding the head end door closed, such views being taken inV the direction indicated by the arrow C of Fig. 4, Fig. 6 showing the latch in operative position and Fig. 7 show.-

, ing the latch as disengaged from its holding lug; and r Fig. Sis a side elevation of a controlling cam employed in the device. r n

vReferring to the drawings the numeral 1 indicates a portion of the head end ofthe Vframe of the spinning machine, one of the headend doors being indicated at 2, such door being pivotally mounted at the point 3.

A second dooris indicated at 4, such door.

-videdwith a latch slioulderl which normally engages thecsurface 14 of the lug projecting from the flange 15 of the frame. A spring 16 normally serves to hold thelatch in locking position, but by inserting the iingers in the recess 9, behind the handle element 11, the lattermay kbe drawn forwardly to release the latch. f

. The draft gearingbonnet 6 is provided i with adepending flange 17 having a laterally extending lug 18 providing the stop element 19. A second lug, spaced from the lug 18, is furnished with a curved cam surface 2O fora purpose hereinafter to be described.

At a point substantially opposite the pivotal connections'of the doors 2 and 4 to the frame, the latter is provided with an opening 21 through which extends a guide housing 22 (Fig. 5) having 4ay flange y23 through which pass bolts 24 for securing it to the face of the frame. r'lhis guide lhousing is furnished with spaced vertical flanges vof duplicate construction, the cam 31 being shown in detail in Fig. 8. As therein shown this cam has the upper and lower substantially parallel cani faces 33, 34, such faces having vthe inclined continua-tions 35, 36 converging toward each other. clined faces terminate iny abrupt shoulders` These in- 37, 88 respectively, fromwhich extend the parallel surfaces 39, 40. The cam carrier is provided with a central vertical slot 41 into which projects a link 42 pivoted to the carrier at 43 and pivota-lly connected at its opposite extremity at the point 44 to the upper arm 45 of the lever device pivoted at 46. The lower arm 47 of this lever device has a link 48 pivotally connected thereto at the point V49, such link in turn being pivotally secured at the point 50 to a. lug or bracket 51 secured to the end of the shipper rod 52. liVith this arrangement it is evident that upon movement. of the shipper rod from the full line position of Fig. to the dotted line position thereof, the cam carrier will also be moved from the full line position to the dotted line position of said figure.

The frame is further provided with an opening 53 over which extends a cover plater 54 secured in position by means of bolts This cover plate serves to support a Vpair of shouldered bolts 56, 57 which serve respectively as the pivots for a pair of bell crank levers comprising -arms 58, 59 respectively. These arms extend in the same gen-v eralV direction, diverging somewhat from `their pivotal points and at their outer extremities are furnished with adjustable pins 60, 61 secured in position by means of set screws 62, 63. These pins constitute cam followers engaging the opposite cam faces of the 'cam 31. A. similar pair of levers, theI vend portions 64, 65 only of which are vherein shown, are also provided, such levers having the cam followers 66, 67 engaging the oppositeJ cam faces of the cam 32. The bell crank lever, of which the member 59 constitutes one arm, is provided with a second arm. 68 to the extremity of which is secured a bracket 69. This bracketis provided with an 'inclinedcam face 70, a substantially vertical surface 71 in continuation thereof, and with a lug l72 outstanding from such vertical surface. parts are in ruiming position as shown in Fig. 1, lies in the path of movement of the arm 12 of the latch device hereinbefore described, the normal position of the end of such latch being indicated by the dotted rectangle 12a in Fig. 1. The parts are also shown in a similar position in Fig. 6 wherein the lug 72 is indicated as lying behind the arm 12, In this position of the I parts it is'manifestly impossible to swing the arm 12 about its pivot 10 to an extent suflicient to disengage the shoulder 13 from the element 14 so that with the parts so disposed the head end door can not be Y opened.

This lug 72 when the 74 through the frame. At its extremity the arm 73 is provided with a linger 75 which projects transverse-ly throught-he opening 74 and which normally overlies the stop surface 19 of the lug 18y hereinbefore described. 'lhe .lever arms 68 and 7 3 are provided with lugs 76. 77 respectively having a compres sion spring 7 S disposed therebetween. This compression spring normally tends to swing the arms 68 and 73 in opposite directions, such movement however, being limited by the engagement of the pins 60, 61 with the cam surfaces of the cam 31. l y

ll nen the parts occupy the positons shown in Figs. 1 and 6, and in full lines in Fig. 5, `the cam 31 is so disposed that the pins 60, 61 engage the cam surfaces 33, 34 thereof, it being understood that with the parts in this position the belt shifter has moved the belt onto the fast pulley and the machine is in operation. As previously described, when the parts occupy this position, it is impossible to swing the latch arm 12 in such manner as t0 permit opening of the head end door, while at the same `time the linger 75 which overliesthe stop surface of the lug 18 serves to preventopening of the draft gearing bonnet 6.V then the'belt shifter rod 52 is actuated to shift the belt onto the loose pulley to bring the machine to rest, the cam carrier 30 is so moved as to carry the cam 31 into the po` sition indicated in dotted lines in Fig. 5. The pins 60 and 6l pass down the inclined faces 35 and 36 of the cam during 'such movement of the latter until they occupy positions such as indicated in dotted lines 'at 602, 60h, Fig. 5, the spring 78 acting during the movement of the cam to maintain the pins in contact therewith. During such movement of the pins 60 and 61 the arm 68 and 73 move into the positions indicated in Fig. 2. In the latter figure the lug 72 is shown as having passed downwardly from the plane of movement of the end of the latch arm 12 while the inclined surface of the bracket 69 has been brought into contact with such "latch arm (Fig, 7). At the same time the linger 75 has been swung from over the lug 18 and rests 'against the cam surface 20. The engagement of the finger with this surface,

and of the inclined surface 70 with the latch arm 12 serves to prevent the pins 60 and 61 respectively from dropping into contact with the surfaces 89, 40 of the cam 31. W hen however, the head end door and the bonnet are opened as may now be done freely, the latch arm '12 moves over to the po sit-ion indicated in dotted lines at 12b, Fig. 3 thereby ,permitting the arm 68 to move downwardly to the position shown inFig. 2. At the same time the movement of the bonnet upwardly causes the cam surface 201e move from behind the finger thus permitting the arm -73 tor move upwardly to a further extent. Such movement of the lever devices permits the pins 60 and 6l to drop behind the shoulders 37, 38 of the cam 3l. ln this position of the parts, movement of the cam by means of the belt shifter rod 52 is positively prevented so that any movement of the belt shifter such as would carry the belt onto the fast pulley for starting the machine is impossible.

'lVhen however, the head end door and the bonnet are closed the movement of the latch arm l2 under the impulse of the spring 16 serves, by engagement with the cam surface 70, to lift the arm 68 slightly and likewise the cam surface 2O moves the finger 75 and the arm 73back to the position of Fig@ 2. These movements lift the pins 60 and 6l from behind the shoulders 37 and 33 of the cam 31 whereby it is made possible to move the belt shifting rod 52 to carry the belt onto the driving pulley. Y During the initial part of this movement, the pins 60 and 6l travel up the inclined surfaces 35 and 36 of the cam 31 until they rest in running position upon the parallel surfaces 33, 34 thereof.

While the specific arrangementvof parts as herein shown is provided, it is to be understood that various changes and modifications both in the shape and location of the several elements may well be made without departing from the Spirit of the invention.
